Ikaho Onsen Fukuya is a traditional Japanese ryokan situated in Ikaho Onsen, a historic spa town on the slopes of Mount Haruna in Shibukawa City, Gunma Prefecture, approximately 110 kilometres northwest of Tokyo. Ikaho is distinguished by its famous 365-step stone staircase, lined with souvenir shops, ryokan, and street food stalls, and the inn sits within easy walking distance of this central promenade as well as the Ikaho Shrine at the top of the steps.
The property draws on two distinct Ikaho spring sources: the iron-rich ochre-brown spring (chairo no yu), which imparts a distinctive amber hue to the bath water and is valued for dermatological benefits, and the colourless slightly alkaline white spring (shiro no yu). Both spring types are piped into the inn's baths, offering guests the opportunity to experience both Ikaho spring varieties in a single stay—a feature specific to inns with access to both sources.
Guest rooms comprise Japanese tatami layouts and Japanese-Western combination rooms that blend floor-level futon sleeping with a Western-style sitting area. Nightly rates include a full kaiseki dinner and Japanese-style breakfast served in the room or the dining hall. Menu items change with the seasons, incorporating river fish, mountain vegetables, and locally produced miso and pickles characteristic of the Gunma inland region.
The inn's outdoor bath faces a garden space, providing year-round open-air bathing with views of foliage in autumn and snow-dusted pine in winter. A separate indoor communal bath area is segregated by gender. The front desk staff assist with taxi and transport connections for international guests. Ikaho Onsen is accessible by bus from Shibukawa Station on the JR Jōetsu Line in approximately 25 minutes; the nearest Shinkansen station is Takasaki, about 30 minutes further south. The surrounding area offers Haruna Lake and Haruna Shrine approximately 15 kilometres west, both reachable by bus.

Frequently asked questions
What is special about Ikaho's brown spring water?
Ikaho's chairo no yu (brown spring) is rich in iron and radium minerals, giving the water a characteristic amber-brown colour. It has been used for centuries and is traditionally associated with benefits for skin conditions, fatigue recovery, and post-surgery recuperation.
How do visitors reach Ikaho Onsen Fukuya from Tokyo?
Take the JR Jōetsu Line express from Ueno to Shibukawa (approximately 90 minutes), then a bus to Ikaho Onsen (25 minutes). Alternatively, highway buses run directly from Shinjuku to Ikaho in around 2.5 hours. The inn is a short uphill walk from the main Ikaho bus stop.
Are meals included in the room rate?
Yes. Standard room rates at Fukuya include a kaiseki dinner and a Japanese-style breakfast. The menu changes seasonally and is served in the room or the inn's dining area.
Is the outdoor bath available in winter?
Yes. The outdoor rotenburo operates year-round, including winter. Bathing in the open-air while surrounded by snow is considered one of the finest seasonal experiences at Ikaho Onsen.
